Leopold® FilterView SCADA Software

The Leopold® FilterView SCADA software integrates multiple controllers and is designed to keep a constant watch on the essential parameters of the processes in your filter plant. The easy-to-use software provides monitoring and control as part of the Leopold® FilterWorx® system, and can automatically adjust flow rates, initiate and control the backwash sequence, and maximize filter run times.

Leopold® SFC 2000® Supervisory Filter Control System

The Leopold® SFC 2000® Supervisory Filter Control System is designed to continuously monitor and automatically control filter operation and backwash sequencing in water and wastewater treatment plants. The SFC 2000 brings PC-based control, operator interface, and data acquisition to the filter gallery. It is a totally integrated control system that can operate independently as a stand-alone filter controller, function as a supervisory SCADA system, or be easily integrated into a new or existing plant-wide process control and information network.

Leopold® AFC 5000® Filter Control System

The Leopold® AFC 5000® Filter Control System is designed to automatically control and monitor water and wastewater filter operation and backwash sequence. It is a totally integrated system that consists of the control console, programmable controller hardware, and software. The AFC 5000 can operate in either automatic or semi-automatic modes with provision for complete manual backup. It can operate completely independent from SCADA systems, or as an integral unit of a local area network.

Leopold® Simplex SFH Venturi Flow Element

Designed for liquid, gas, or steam service, the Leopold® Simplex SFH venturi produces constant acceleration from main to throat. The rectangular hyperbola forming the inlet curve does not become tangent to the throat diameter. Flow reaches maximum velocity at the throat without further acceleration, providing a constant coefficient curve.

Leopold® Valve PAC® Electronic Valve Positioner/Controller

The Leopold® Valve PAC® Electronic Valve Positioner/Controller is a single-loop controller specifically designed to provide automatic rate-of-flow control of various flows in a water treatment plant, but can be used on a wide range of process control applications. It can be panel-mounted on a new or existing console, or mounted locally at the valve.

Valve PAC is especially suited for controlling the effluent flow valve in manual, automatic, and remote modes. Its simple design allows for easy transitioning between modes of filtration operation, such as declining rate, constant rate, and constant level.
